5.2 Matching Circuit

Like all antennas, surrounding components, enclosures, and changes to the GND plane

dimensions can alter performance. A pi-matching network like the one shown below is required

in case adjustments need to be made. The antenna EVB has a similar matching network. The

components on the EVB are a good starting point for a new design, but will need to be adjusted

upon integration for best performance. The zero ohm resistor is needed for the ability to solder

down a coax pigtail to make measurements with a vector network analyzer.
